Seasoned observers of the United Nations generally regard the organisation’s lofty aspirations to the “betterment of humankind” and the eternal pursuit of “peace and security” as just the rhetorical tokens…

Author Douglas Adams famously had his Hitchhiker’s Guide to the Galaxy remark that “space is really big”. But to my mind the sheer vastness of space is better encapsulated in the recent announcement of…
In the Star Wars universe, everyone’s favourite furry aliens, the Ewoks, famously lived on the “forest moon of Endor”. In scientific terms, the Ewok’s home world would be referred to as an exomoon, which…
The cosmological community is bubbling with the news that the BICEP2 experiment may have detected gravitational waves through measuring the radiation left over from the big bang. If the findings are correct…
After its successful launch in December, European Space Agency’s (ESA) Gaia has now taken up its position in space and is ready to survey the skies. With the help of two onboard telescopes focused onto…
Our unfolding understanding of the universe is marked by epic searches and we are now on the brink of discovering something that has escaped detection for many years. The search for gravity waves has been…
Mercury has long been a mystery to scientists. Until recently, knowledge of the planet was limited to the grey, patchy landscape revealed by the Mariner 10 probe, NASA’s first mission to Mercury in the…
Out of hibernation, Rosetta stirs at last. As one of the scientists involved in the mission, news that the unmanned spacecraft has woken up and restored contact with Earth comes as a great relief. It contains…
A famous picture in the English edition of Newton’s “Principia” shows cannon balls being fired from the top of a mountain. If they go fast enough, their trajectory curves downward no more steeply than…
Clays and geysers! All we need is a regular flight and Europa will become a spa destination to rival Iceland. It’s been an exciting week for me at the annual American Geophysical Union conference in San…
Comet ISON’s fate has left many sad. For the public, the comet could have made for a spectacular view in December. For scientists, it would have been a chance to learn more about these mysterious bodies…
Habitation of outer space needs solving air, water, energy and food supplies within a tight space. And this isn’t a problem of an apocalyptic, remote future. Developing this technology addresses some of…
With India and China planning lunar surface missions, privately-funded space entrepreneurs competing for the US$40 million Google Lunar X Prize and discussions around lunar mining intensifying, working…
It seems like science fiction that 44 years ago Apollo 11 astronauts Armstrong and Aldrin traveled nearly a quarter of a million miles to walk on the surface of the Moon. When the crew of Apollo 17 returned…
Following India’s maiden Mars probe launch earlier in the month, last week saw the successful launch of the Martian Atmospheres and Volatiles Evolution mission, or MAVEN for short. With the second spacecraft…
Comet ISON is in danger of disintegration according to new observational data conducted by the Group of Computational Physics…
The Observer has published what it regards as the top 20 questions in Science. Number one on the list is the question of what the universe is made of. Specifically the 95% of the universe that we cannot…
Analysis of fragments of the Chelyabinsk meteorite shows it either collided with another body before hitting the atmosphere…
Space is Big. Really Big. The Hitchhiker’s Guide to the Galaxy pretty much nailed space with those five words. And space is so really big that our earthly measures of distance struggle. The distance to…
The United Nations’ Committee on the Peaceful Uses of Outer Space is meeting in Vienna this week, and representatives of 74 countries will discuss, among other things, how to ensure space is maintained…
